Components: What Makes Up Your Roof

A roof is one of the most functional and important aspects of your home. Its purpose is to protect you, your family, and all of your possessions from the outside elements, more specifically, water. Water is your roof’s worst enemy, which is why roofs are carefully constructed to keep water out, at all costs. Read on to learn more about what makes up your roof and why each component is necessary.


Shingles, while extremely functional, are also a great way to incorporate design and style into your home. Shingles are made of asphalt or fiberglass and they come in a plethora of designs, colors, thicknesses, and textures. You can accomplish any layout with shingles. Whether it is cottage style, Italian rustic, or modern, shingles can do it all.

Shingles add more than just a beautiful touch, they are the first line of defense against the outside elements. Water and debris are the culprits to almost all roofing issues, so shingles are absolutely crucial in protecting the structure of your roof.


Decking is usually made from ½-inch plywood and is yet another protection factor for your roof’s structure. The decking reinforces the roof’s integrity and is also used as a nail bed for shingles. The decking is a second layer of reassurance against the wind, water, and debris.

Underlay Membrane

The underlay membrane is a coating made of felt, either saturated with asphalt or a synthetic fabric. The membrane protects the shingles against resin produced by the wood decking while simultaneously protecting the decking material.

Eaves Membrane

The eaves membrane, located directly under the shingles, prevents water infiltration. When exposed to direct water and sunlight, like our Florida roofs, proper roof inspection of the eaves membrane is crucial in preventing water damage.

Attic Ventilation

Attic ventilation is mostly used for keeping excess heat and moisture out of your attic, ultimately protecting the integrity of your roof’s structure. The ventilation also plays a significant role in keeping the inside of your home cool and comfortable. Without proper ventilation in a place like West Palm Beach, your electric bill would be through the roof. Attic ventilation helps maintain proper temperatures for a longer amount of time.


Flashing is a material made of galvanized steel, aluminum or plastic and can either be flexible or stiff. This water-resistant molding, once again, prevents water from entering the roof’s structure. Like every element in a roof’s structure, flashing is designed to keep water infiltration from occurring.

Every component of your roof’s structure is created to keep water out. Water and the outside elements will destroy the integrity of your roof and each roofing element is important and necessary to the health of your roof, which is why proper roof maintenance and inspection is absolutely crucial.
